本考案は、主として軸方向の入力振動を防振する流体封入式筒型マウントに係 り、特に入力される振動荷重に対する強度が有利に発揮され得て、所期の防振特 性を安定して得ることのできる流体封入式筒型マウントの構造に関するものであ る。 This invention mainly relates to a fluid-filled cylindrical mount that isolates input vibrations in the axial direction. In particular, the strength against the input vibration load can be advantageously exhibited, and the desired vibration isolation characteristics can be achieved. This article concerns the structure of a fluid-filled cylindrical mount that can provide stable performance. Ru.

従来から、振動伝達系を構成する部材間に介装されて、それら両部材を防振連 結するマウントの一種として、互いに径方向に所定距離を隔てて配された内筒金 具と外筒金具とが、それらの間に介装されたゴム弾性体にて連結されてなる構造 を有し、主として内外筒金具間に入力される軸方向振動を防振するものが知られ ており、例えば、自動車のサスペンション用アッパサポートやストラットバー・ クッション、テンションロッド・ブッシュ、ボデーマウント等として、好適に用 いられている。 Traditionally, it has been inserted between the members that make up the vibration transmission system, and has been used to connect these two members to a vibration-isolating connection. As a type of mount for connecting the A structure in which the fitting and the outer cylindrical fitting are connected by a rubber elastic body interposed between them. It is known that the axial vibration that is input between the inner and outer cylindrical metal fittings is mainly damped. For example, it is used for automobile suspension upper supports, strut bars, etc. Suitable for use as cushions, tension rods/bushes, body mounts, etc. I'm tired.
【０００３】 また、このような筒型マウントには、近年の車両の高級化に伴って、より高度 な防振性能が要求されるようになってきており、その一つの対応策として、流体 の封入化が検討されてきている。そこで、本願出願人は、先に、実願平１−９９ ０１２号において、自動車用アッパサポートに好適に採用される流体封入式の筒 型マウント構造を提案した。0003 In addition, as vehicles have become more sophisticated in recent years, these cylindrical mounts have become more sophisticated. There is a growing demand for vibration-proofing performance, and one way to address this is by using fluid The encapsulation of these materials is being considered. Therefore, the applicant of the present application first filed the application In No. 012, a fluid-filled cylinder suitable for use in upper supports for automobiles is disclosed. A type mount structure was proposed.
【０００４】 かかる流体封入式筒型マウントは、軸直角方向外方に突出する環状の羽根部が 軸方向中央部に設けられた内筒金具の外側に、該内筒金具の羽根部に対して軸方 向に対向位置する環状の支持部と、該支持部の外周縁部から軸方向内方に突出す る筒状の取付部とを有する一対の取付金具を、軸方向に互いに所定距離を隔てて 対向配置せしめて、それら内筒金具と取付金具とをゴム弾性体にて連結すると共 に、該ゴム弾性体によって、かかる一対の取付金具における取付部間を通じて外 周面に開口する、底部から前記内筒金具の羽根部が突出せしめられた環状の空所 を形成し、更に、該一対の取付金具の外周面に外筒金具を嵌着せしめて空所の開 口を覆蓋することにより、前記羽根部によって軸方向中央部分が狭窄された環状 の流体室を形成せしめてなる構造とされている。そして、このようなマウントに あっては、内外筒金具間に軸方向の振動が入力された際、流体室内に生ぜしめら れる流体の共振作用に基づいて、ゴム弾性体のみでは得られない、優れた防振効 果が発揮されることとなるのである。0004 Such a fluid-filled cylindrical mount has an annular blade portion that protrudes outward in the direction perpendicular to the axis. On the outside of the inner cylindrical metal fitting provided at the center in the axial direction, there is a an annular support portion located opposite to each other; and protruding inward in the axial direction from the outer peripheral edge of the support portion. A pair of mounting brackets each having a cylindrical mounting portion are spaced apart from each other by a predetermined distance in the axial direction. By arranging them facing each other, and connecting the inner cylindrical fitting and the mounting fitting with a rubber elastic body. The rubber elastic body allows the external part to pass between the mounting parts of the pair of mounting brackets. an annular cavity that is open to the peripheral surface and has a bottom portion from which the blade portion of the inner cylindrical metal fitting protrudes; , and further, fit an outer cylindrical metal fitting onto the outer circumferential surface of the pair of mounting fittings to open the hollow space. By covering the mouth, an annular shape whose central portion in the axial direction is narrowed by the wing portion is formed. The structure is such that a fluid chamber is formed. And in a mount like this If axial vibration is input between the inner and outer cylindrical metal fittings, the vibration generated in the fluid chamber. Based on the resonance effect of the fluid in the The results will be realized.
【０００５】 ところが、本考案者らが更なる検討を加えたところ、かかる流体封入式マウン トにおいては、その取付金具が、互いに軸方向に所定距離を隔てて対向位置せし められる一対の分割構造をもって構成されており、取付部の外周面に嵌着される 外筒金具によって一体化されて成る構造とされているが、かかる外筒金具による 保持構造では、それら一対の取付金具の軸方向における保持強度が充分に得られ 難いことが、明らかとなった。[0005] However, upon further study by the present inventors, they discovered that such a fluid-filled mount In the case of It is configured with a pair of split structures that can be fitted onto the outer circumferential surface of the mounting part. Although the structure is integrated with an outer cylinder metal fitting, The holding structure does not provide sufficient holding strength in the axial direction of the pair of mounting brackets. It became clear that it was difficult.
【０００６】 すなわち、それら一対の取付金具における相対的な離隔方向における変位は、 外筒金具によるかしめ固定や取付ブラケットによるストッパ構造等によって規制 することが可能であるが、相対的な接近方向における変位を規制することが極め て困難であったのであり、それ故、かかるマウントに対して大きな振動荷重が入 力された際に、それら一対の取付金具の接近方向への変位により配設間隔が狭く なって、ゴム弾性体や流体室が変形してしまい、マウント特性が変化して所期の 防振特性が有効に得られなくなる恐れがあったのであり、この点において、未だ 改良の余地を有していたのである。[0006] In other words, the relative displacement of the pair of mounting brackets in the direction of separation is: Regulated by caulking fixation using outer cylinder metal fittings, stopper structure using mounting bracket, etc. However, it is extremely difficult to control displacement in the direction of relative approach. Therefore, large vibration loads are applied to such mounts. When force is applied, the pair of mounting brackets move toward each other, resulting in narrower installation spacing. As a result, the rubber elastic body and fluid chamber may be deformed, and the mount characteristics may change, causing the desired There was a risk that the anti-vibration characteristics could not be obtained effectively, and in this respect, there is still no There was room for improvement.
【０００７】[0007]
ここにおいて、本考案は、上述の如き事情を背景として為されたものであって 、その解決課題とするところは、軸方向に所定距離を隔てて配置された一対の取 付金具における軸方向の位置決めが充分な耐荷重強度をもって為され得て、所期 の防振特性が有効に且つ安定して発揮され得る、改良された構造の流体封入式筒 型マウントを提供することにある。 Here, this invention was made against the background of the above-mentioned circumstances. , the problem to be solved is a pair of mountings placed a predetermined distance apart in the axial direction. The axial positioning of the fittings can be done with sufficient load-bearing strength, and the desired A fluid-filled cylinder with an improved structure that can effectively and stably exhibit the vibration-proofing characteristics of The purpose is to provide a type mount.

【００１９】 また、この密閉された空所３２には、前記外筒金具３４の一体加硫成形品に対 する外挿、縮径操作が流体中にて行なわれること等によって、所定の非圧縮性流 体が封入されており、それによって環状の流体室が形成されている。なお、かか る封入流体としては、後述する如き、流体の流動に基づく防振効果が有効に発揮 され得るように、０．１Pa・s 以下の粘性率を有する低粘性流体を用いることが 望ましく、例えば水やアルキレングリコール、ポリアルキレングリコール、シリ コーン油等が好適に用いられる。[0019] Further, in this sealed space 32, there is provided an integrally vulcanized molded product of the outer cylindrical fitting 34. A given incompressible flow is A body is enclosed thereby forming an annular fluid chamber. In addition, As a sealed fluid, the vibration damping effect based on the fluid flow is effectively exhibited, as described below. It is possible to use a low viscosity fluid with a viscosity of 0.1 Pa・s or less so that Desirably, for example, water, alkylene glycol, polyalkylene glycol, silicon Corn oil and the like are preferably used.
【００２０】 さらに、このような非圧縮性流体が封入された流体室は、その軸方向中央部に 位置せしめられた前記羽根部１４によって略二分されている。それによって、該 羽根部１４を挟んだ軸方向両側には、一対の環状の分割流体室３６，３６が形成 されていると共に、かかる羽根部１４の突出端面と外筒金具３４との径方向対向 面間において、それらの分割流体室３６，３６を相互に連通する環状の狭窄部３ ８が形成されている。[0020] Furthermore, the fluid chamber filled with such an incompressible fluid has a central part in its axial direction. It is approximately divided into two by the positioned blade portion 14. Thereby, the applicable A pair of annular divided fluid chambers 36, 36 are formed on both sides of the blade portion 14 in the axial direction. At the same time, the protruding end surface of the blade portion 14 and the outer cylindrical fitting 34 are radially opposed to each other. An annular constriction portion 3 that communicates the divided fluid chambers 36, 36 with each other between the surfaces. 8 is formed.
【００２１】 そうして、このような構造されたアッパサポートにあっては、更に、その外筒 金具３４に対してブラケット４０が取り付けられている。かかるブラケット４０ は、それぞれ、軸方向一端側の開口部に外フランジ部４２が、軸方向他端側の開 口部に内フランジ部４４が、それぞれ形成された円筒形状を呈する上下筒金具４ ６，４８によって構成されており、それら上下筒金具４６，４８が、それぞれ、 外フランジ部４２の形成側開口部において、外筒金具３４の軸方向両側から外嵌 せしめられ、両外フランジ部４２，４２が一体的に重ね合わされることによって 組付けられている。また、かかるブラケット４０の外フランジ部４２，４２には 、３本のボルト５０が植設されており、これらのボルト５０によって、上下筒金 具４６，４８が一体的に重ね合わされた状態で、図示しない車体側に固定的に取 り付けられるようになっている。[0021] In an upper support structured like this, the outer cylinder is also A bracket 40 is attached to the metal fitting 34. Such a bracket 40 The outer flange portion 42 is located at the opening on one axial end side, and the outer flange portion 42 is located at the opening on the other axial end side. Upper and lower cylindrical metal fittings 4 each having a cylindrical shape and having an inner flange portion 44 formed at the mouth thereof. 6, 48, and these upper and lower cylindrical fittings 46, 48, respectively, At the formation side opening of the outer flange portion 42, the outer cylinder fitting 34 is fitted from both sides in the axial direction. and both outer flange parts 42, 42 are integrally overlapped. It is assembled. Further, the outer flange portions 42, 42 of the bracket 40 include , three bolts 50 are installed, and these bolts 50 connect the upper and lower cylinder metals. The tools 46 and 48 are fixedly attached to the vehicle body (not shown) in a state where they are integrally overlapped. It is designed to be attached.
【００２２】 また、そのような組付状態下、かかるブラケット４０は、その上下筒金具４６ ，４８における内フランジ部４４，４４が、取付金具１８，１８における支持部 ２０，２０の外側面に対して、それぞれ重ね合わされており、それによってそれ ら取付金具１８，１８を軸方向に挟持するようになっている。即ち、このブラケ ット４０にて、取付金具１８，１８が軸方向に挟持されることにより、それら取 付金具１８，１８の外筒金具３４からの抜け出しが防止されると共に、それら取 付金具１８，１８における離隔方向への相対的な変位が阻止されるようになって いるのである。[0022] In addition, under such an assembled state, the bracket 40 has its upper and lower cylindrical fittings 46 , 48, the inner flange portions 44, 44 in the mounting brackets 18, 18 are superimposed on the outer surfaces of 20 and 20, respectively, thereby The mounting fittings 18, 18 are held between them in the axial direction. In other words, this bracket The mounting brackets 18, 18 are held in the axial direction by the cutter 40, so that they can be mounted. This prevents the attachment fittings 18, 18 from coming off the outer cylinder fitting 34, and also prevents them from being removed. Relative displacement of the fittings 18, 18 in the separating direction is prevented. There is.
【００２３】 そして、このような構造とされたアッパサポートにあっては、内外筒金具１０ ，３４間に軸方向の振動が入力された際、羽根部１４の変位に基づいて、分割流 体室３６，３６間に相対的な容積変化が惹起されることとなる結果、それら分割 流体室３６，３６間において、狭窄部３８を通じての流体の流動が生ぜしめられ ることとなり、以て、この狭窄部３８内を流動せしめられる流体の共振作用に基 づいて、所定の防振効果、例えば車両乗り心地を向上するために問題となる中乃 至高周波数域の入力振動に対する低動ばね効果が、有利に発揮され得るのである 。なお、この流体の共振作用に基づいて発揮される防振効果は、狭窄部３８の長 さや開口面積を調節することによってチューニングされることとなる。[0023] In the upper support having such a structure, the inner and outer cylindrical fittings 10 , 34, the split flow is divided based on the displacement of the blade portion 14. As a result, a relative volume change is caused between the body chambers 36, 36, and the division thereof A fluid flow is generated between the fluid chambers 36 and 36 through the constriction portion 38. Therefore, based on the resonance effect of the fluid flowing inside this constricted portion 38, Therefore, it is necessary to improve the vibration damping effect, for example, to improve vehicle riding comfort. The low dynamic spring effect against input vibration in the highest frequency range can be advantageously exerted. . Note that the vibration damping effect exerted based on the resonance effect of the fluid depends on the length of the narrowed portion 38. Tuning is achieved by adjusting the sheath opening area.
【００２４】 それ故、かかるアッパサポートによれば、車両走行時におけるロードノイズ等 の騒音や振動が極めて有効に低減せしめられ得、良好なる車両乗り心地が有利に 実現され得るのである。[0024] Therefore, according to such an upper support, road noise etc. when the vehicle is running can be reduced. The noise and vibration of the vehicle can be extremely effectively reduced, resulting in a good vehicle ride comfort. It can be realized.
【００２５】 しかも、上述の如き構造のアッパサポートにおいては、軸方向に所定距離を隔 てて対向配置された取付金具１８，１８が、その取付部２１，２１に形成された 脚部２２，２２によって軸方向に互いに当接されており、その接近方向への変位 が防止されていることから、内外筒金具１０，３４間に大きな振動荷重が入力さ れた際にも、それら取付金具１８，１８が相対的に接近するようなことがない。 そして、それ故、取付金具１８，１８の相対的な位置ずれに起因する防振特性の 変化が完全に防止され得ることとなり、所期の防振特性が安定して発揮され得る こととなるのである。[0025] Moreover, in the upper support having the structure described above, Mounting fittings 18, 18 arranged opposite to each other are formed on the mounting parts 21, 21. The legs 22, 22 abut each other in the axial direction, and the displacement in the approaching direction This prevents large vibration loads from being input between the inner and outer cylindrical fittings 10 and 34. Even when the mounting brackets 18, 18 are installed, the mounting brackets 18, 18 do not come close to each other. Therefore, the vibration damping characteristics due to the relative positional deviation of the mounting brackets 18, 18 Changes can be completely prevented, and the desired anti-vibration properties can be stably exhibited. That's what happens.
【００２６】 また、本実施例においては、ブラケット４０，４０の内フランジ部４４，４４ により、取付金具１８，１８の離隔方向への変位も防止されていることから、そ れら取付金具１８，１８の離隔方向への変位に起因する防振特性の変化も、極め て有利に防止され得るのである。[0026] Further, in this embodiment, the inner flange portions 44, 44 of the brackets 40, 40 This also prevents the mounting brackets 18, 18 from being displaced in the direction of separation. Changes in vibration isolation characteristics caused by displacement of the mounting brackets 18, 18 in the direction of separation are also extremely This can advantageously be prevented.
【００２７】 加えて、本実施例におけるアッパサポートにあっては、ゴム弾性体２４を介し て取付金具１８に連結された内筒金具１０の外周面が、テーパ面１６として形成 されており、内外筒金具１０，３４間にこじり方向の振動荷重が入力された際に おけるゴム弾性体２４の変形が、主に剪断変形として生ぜしめられるようになっ ていることから、こじり方向に入力されるの振動荷重に対しても、柔らかいばね 特性が有利に発揮され得ることとなって、サスペンション機構の作動の円滑化が 図られ得るのであり、それによって車両乗り心地の向上が、一層有利に達成され 得ることとなるのである。[0027] In addition, in the upper support in this embodiment, the rubber elastic body 24 The outer peripheral surface of the inner cylinder fitting 10 connected to the mounting fitting 18 is formed as a tapered surface 16. When a vibration load in the prying direction is input between the inner and outer cylindrical fittings 10 and 34, The deformation of the rubber elastic body 24 is now mainly caused by shear deformation. Because of this, a soft spring can withstand vibration loads input in the prying direction. The characteristics can be utilized advantageously, and the operation of the suspension mechanism can be made smoother. As a result, the vehicle ride comfort can be improved even more advantageously. You will get it.
